Swap X Y in RPN Mode

[Mgerbasio]

I dusted off the HP Prime and updated it to the latest firmware on the HP site. I've been using HP calculators since the 41C and they've all had a dedicated button to swap X Y registers. It annoying without it using RPN at least for me. Probably why it's been been sitting in a desk drawer.
Is there another solution other than hitting enter to load the number on the stack and use roll down? Can I assign a program to a key I down use anymore? The custom labels for the keys on the 41C would be handy for this

Thanks.
